I have a 7lb chihuahua mix and 20lb whippet mix (the breeds are guesses as they were both rescues), who are about 8 months old. I have been feeding them Canidae ALS. They also get a whole raw egg a couple of times a week. However both of them are itchy and seem to shed a lot for short-haired dogs. I bathe them approximately twice a month with earthbath aloe and oatmeal, which seems to have actually helped with the itching. They are both primarily indoor apartment dogs (except for walks, dog park trips, etc.), plus they are totally different breeds so I don't think it's allergy related. I was wondering if there is something I could add to their food to help with their coats? Please don't tell me to switch to some fancy expensive food, if I had the money they would be on the best of the best, but I can't, so I try to do the best I can with what I have.
